SPRING-GUN.

Specification of Letters Patent.

Patented Oct. 20, 1914.

Application filed May 31, 1913. Serial No. 771,033.

T0 all whom it may concern:

Be it known that I, `WILLIAM E. HAW- THORNE, a citizen of the United States of America, residing at Plymouth, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Spring-Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to spring guns in which the power for propelling the projectile is first stored by manual manipulation.

It is one of the objects of the invention to provide an actuating mechanism for the power storage, which simulates the .so-called pump mechanism employed on cartridge guns.

It is a further object to obtain a construe` tion having certain advantageous features as hereinafter set forth.

In the drawings: Figure 1 is an elevation of the gun; Fig. 2 is a longitudinal section through a portion of the barrel, showing the power storage mechanism in its initial position; and Fig. 3 is a similar view showing the power stored but before the return of the parts to position for firing, and also showing in dotted lines the said parts returned.

A is the barrel of the gun, B is the power storage spring therein, C an abutment aga-inst which said spring bears, D a plunger, and E the plunger shank extending through said abutment and provided with a head F/ for engaging the scar F. The gun belongs to that type in which the spring is compressed by a forward movement of the abutment, which is subsequently returned lafter engagement of Uhe shank with the sear. Such guns are, however, usually operated by levers, while with the present invention, as above stated, a longitudinally slidable actuating mechanism is provided, the construction being as follows:

' The abutment C is mounted in a hollow slide G, which is movable longitudinally of the barrel and is provided with a rack H preferably formed by pins extending between the opposite sides of the slide. I is a segmental rack engaging the rack H, which is pivoted at J and is provided with a forwardly-extending arm K connected by a pivotal link L with an actuating member M. This actuating member is a block or hand grip, which is slidable longitudinally of the barrel, being preferably mounted upon arodO arrange parallel to the barrel. Thus, by pulling rearward upon the member M, the link L and arm K will swing downward partially rotating the segmental rack I and moving the rack I-I and slide G forward. This will advance the sear which is pivotally mounted at P upon the slide G until it engages with the head E on the shank E. The actuating member is then moved forward again to return the slide G, carrying with it the compressed spring, plunger and shank.

In performing the operation just described, it is important to prevent releasing of the spring before the return of the slide, as otherwise the recoil of said spring would kick the slide backward against the steek Q. Such a result I have guarded against by a construction in which the sear is separable from the trigger and is only in operative relation with the latter when the slide is fully returned. Thus, as shown7 R is the trigger which is tpivoted at R in a fixed position within the gun barrel. The sea-r F, as before stated, is pivoted at P upon the slide G, and a rearwardly-extending arm F lies in the path of the trigger when the parts are in normal position.

S is a spring for yieldably holding the scar in position of engagement.

When the slide is moved forward in the operation above described, the arm F is withdrawn from the path of the trigger It, and therefore any movement of the trigger will be ineffective to discharge the gun until the parts are returned to normal position.

With the construction as described in operation. to sto-re the power the actuating member M is drawn rearward, which will swing downward the links L and arms K, rotating the rack I and moving the slide G forward until the head E engages the scar. The reverse movement of the actuating member M returns the slide and sear to normal position, in which the latter is in the path of the trigger R and consequently upon the pulling of the trigger the plunger is released to be moved forward under the tension of the spring.

What I claim as my invention is:

l. In a gun, the combination of a power storage spring, a trigger, an abutment movable to compress said spring and returnable te its initial position for firing, a sear for engaging the trigger carried by said abutment and in operative relation to be released by the trigger only when' the abutment is in said initial position. y

2. ln a gun, the combination of a power storage spring, an abutment, mechanism for moving said abutment forward to compress said spring and for then returning said abutment to normal position, a trigger for releasing said spring, and a Sear controlling the release 'of ,said spring, separable from said trigger during the forward movement ofl said abutment and restored to operative relation with said trigger upon the return of said abutment.

3; In a gun, the combination of a power storage spring, an abutment therefor, mechanism for moving said abutment forward to compress said spring and to then return the abutment to itsnorinal position, a trigger for releasing said spring, and a Searv movable with said abutment out of operative relation with saldtrigger and restored into operative relation upon the return of said abutment.

4; In a gun, the combination with a barrel, of a'powei storage spring therein, an abutnient movable forward in s'aid barrel to compress said spring and then returnable wihfsaid spring to its initial position, an actuating member slidable parallel to the aXis of said barrel, and connections between said actuating member and abutment for transmitting reciprocato'ry movement vfrom 'vbs'fa'f tim fata-:iis may be steamed mi ve ents the former to th'e latter in reverse directions.

5. ln a gun, the combination with the barrel, of a power storage spring, a slidable abutment for said spring Within said barrel movable forward to compress the spring, a seal' carried by said movable abutment for retaining said spring in compressed condition, an actuating member slidable parallel to the axis of said barrel, connections between said actuating member and said abutment for imparting reverse reciprocatory movement from one to the other, and a trigger from which Said sear is withdrawn in the forward movement of said abutment and to which it is returned by the reverse movement.

6. In a gun, the combination with the ban` rel, of a plunger, a spring for actuating said plunger, a movable abutment other than said plunger for said spring, an actuating member arranged eXterior'ly of the barrel and slidable longitudinally of said barrel, and connections between said actuating member and abutment for moving the latter to' compress the spring upon a rearward movement of the actuating member.

In testimony whereof affix my signature in presence of two witnesses.`
